CMA investigating Worcester Bosch over hydrogen-blend boiler claims, warns 12 other sellers

The Competition and Markets Authority (CMA) is investigating whether boiler maker Worcester Bosch is misleading shoppers with confusing or inaccurate claims about its boilers being ‘hydrogen blend ready’.
The investigation will focus on whether the marketing claims made about these products, which cost £1500 – £3200, and may mislead shoppers into thinking they are more environmentally friendly than they are.
The CMA’s investigation will look at several marketing practices including the use of:
Labels or text stating that Worcester Bosch’s boilers can run on a blend of 20% hydrogen and natural gas, which may give the impression this is a special feature, despite all boilers in the UK being legally required to operate this way since the mid-1990s.
Information and messaging on the use of hydrogen for home heating in the UK – despite this not currently being available and its introduction being potentially years away and dependent on future government decisions.
Descriptions and information about the environmental benefits of ‘hydrogen-blend ready’ boilers which may falsely suggest that these boilers will reduce a household’s carbon footprint.
This action comes as part of the CMA’s wider work looking at the green heating and insulation sector and follows a report earlier this year which highlighted concerns that a number of businesses were making potentially misleading claims online about hydrogen use in boilers. It put the sector on notice for further action.
The CMA has also written to 12 other businesses that sell ‘hydrogen-blend’ boilers, after reviewing their marketing, to warn them that they could be breaching consumer protection law and to remind them of their legal obligations.
George Lusty, Senior Director for Consumer Protection at the CMA, said:
“Businesses need to be clear about the environmental credentials of the products they’re selling. This is especially important for heating products like home boilers, which are an expensive and long-term purchase.
We set out our concerns earlier this year about businesses marketing boilers as ‘hydrogen-blend’. We’ll now be scrutinising green claims from Worcester Bosch to see if they mislead shoppers.
In the meantime, we’ll continue to keep a close eye on practices in the sector.”
